Speed of sound in gases?

Question

Speed of sound in gases?

Answer 1

same as normal, the atmosphere has gas's doesn't it?

A cool fact is that light slows down in certain substances but when it leaves them it speeds up again, weird hey

Answer 2

The speed of sound will vary according to the density of the gas that it's traveling through, and the atmospheric pressure.

Answer 3

c = (kRT)^1/2

c - is speed of sound

k - is gas constant (1.4 for air, 1.667 for noble gases)

R is the universal gas constant

T is the temperature

so for air at 300 Kelvin c is approximately 330 m/s

Answer 4

its 330m/s
